With a soft murmur, Yu Tianheng suddenly noticed something.
Something seemed to be glowing where the remains of the two Dragon Kings lay.
He stepped closer, and when he saw clearly what it was, Yu Tianheng could not help crying out in surprise.
"Soul Bones? The Dragon Kings' Soul Bones!"
On the continent today, Soul Bones were already exceedingly rare.
As for the Dragon Kings' Soul Bones, these two were probably the only ones that could be found.
Yu Tianheng had never imagined he would reap such a reward.
And the two Soul Bones happened to be one for the left and one for the right: the Water Dragon King's left arm bone and the Fire Dragon King's right arm bone.
Without wasting a moment, Yu Tianheng immediately began absorbing the Soul Bones.
His own bloodline had already been evolved by the bloodlines of the two Dragon Kings, making it an almost perfect match for the Soul Bones.
After only half an hour, Yu Tianheng rose to his feet.
Soul Bones truly deserved to be coveted by everyone on the Douluo Continent.
Once they had truly fused with his body, the changes they brought were immense.
[Ding! Congratulations to the host on successfully absorbing the Fire Dragon King and Water Dragon King Martial Souls. The two Dragon King bloodlines within the host are now complete. From now on, the Fire Dragon King and Water Dragon King Martial Souls will automatically generate the most suitable Soul Rings, and the age of those Soul Rings will rise along with the host's Soul Power Level!] [Ding! The increase in the number of Soul Rings in the Blue Dot Tyrant Dragon Clan has reached the required standard. Soul Ring sum feedback issued. The host's Thunder Dragon King Martial Soul has automatically obtained a third Soul Ring! Like the first and second Soul Rings, the third Soul Ring's age is temporarily suppressed.]
After listening to the system's account, Yu Tianheng took a look at the third Soul Ring's Soul Skill.
Indestructible Raging Thunder Body: Once the Soul Skill is released, lightning transforms into indestructible raging thunder capable of destroying heaven and earth. Once it touches something, the indestructible raging thunder cannot be removed. Its power of destruction will continuously inflict damage, and damage already inflicted cannot heal on its own. Unless the user actively recalls it, the indestructible raging thunder will not stop until it has destroyed everything.
Seeing the effect of the third Soul Skill, Yu Tianheng could not help drawing a sharp breath.
With his current strength, even an existence at the Soul Emperor level, once touched by this indestructible raging thunder,
would probably spend the rest of their life in endless agony until death!
After obtaining the third Soul Ring, Yu Tianheng's Soul Power Level kept climbing until it reached level thirty-six.
The main reason was still the benefits brought by absorbing the two Dragon Kings' dragon souls.
If transforming his physique and bloodline had not consumed so much power,
he did not even dare imagine what level he would have reached by now.
He released his Martial Soul and looked at the three Martial Souls, now six thousand years old, circling his feet in layers.
Yu Tianheng let out a long breath.
This trip to the Ice and Fire Yin Yang Well had brought him far too many benefits.
So much time had passed that Yan Yan and Grandpa Dugu were probably getting anxious from waiting.
Yu Tianheng bent his legs slightly and unleashed a tremendous burst of strength.
He even left two small, footprint-sized pits in the lakebed.
Like a bolt of lightning, he shot straight toward the water's surface.
After lunch, Dugu Yan sat down beside the Ice and Fire Yin Yang Well, pouting.
"Tian Heng, when are you coming out? I've been waiting for you for so long."
The moment she finished speaking, a strange disturbance suddenly came from the Ice and Fire Yin Yang Well.
A tremendous spray of water erupted from the surface, and a figure flew out of it.
Dugu Bo, standing nearby, assumed a fighting stance. He thought the owner of the two terrifying presences he had sensed earlier had emerged.
All nine Soul Rings appeared beneath his feet, and the enormous Jade Phosphor Serpent Emperor behind him flicked its tongue repeatedly.
He reached out to shield Dugu Yan behind him.
"Who are you? If the Ice and Fire Yin Yang Well is your territory, we can leave, but please return the child who entered it earlier!"
Although Dugu Bo knew full well that, given his strength, confronting the other party head-on would be like a mantis trying to stop a chariot,
he still wanted to try.
He could not possibly leave Yu Tianheng in the waters of the Ice and Fire Yin Yang Well forever.
"Grandpa Dugu, it's me. I'm back."
Yu Tianheng landed in front of the two of them.
The clothes he had been wearing had all been destroyed during the baptism of the two dragon souls.
These were ordinary clothes he had just changed into, completely different from the clan robes of the Blue Lightning Tyrant Dragon Clan he had worn before.
It was understandable that they had not recognized him at first.
After seeing Yu Tianheng's face, Dugu Bo finally let out a long breath.
But then he spoke in the instructive tone of an elder.
"Tian Heng, the danger of this Ice and Fire Yin Yang Well is beyond anything you can imagine. How could you enter it so rashly?"
Hearing this, Yu Tianheng could not help giving a wry smile.
"Grandpa Dugu, I felt at the time that there might be an opportunity for me in the spring, so I went down. I was wrong not to tell you beforehand."
Yu Tianheng bowed directly to Dugu Bo.
"Grandpa, it's enough that Brother Tian Heng is back. You're not allowed to scold him!"
Having come to her senses, Dugu Yan hurried over as well.
She kept feeling Yu Tianheng all over, checking whether he had been injured over the past half month.
"Yan Yan, I'm fine. Thanks to the Ice and Fire Yin Yang Well, my body was tempered even further."
Yu Tianheng rubbed Dugu Yan's hair and comforted her gently.
But who would have thought those words would shatter the strength Dugu Yan had been putting on all this time?
She threw herself into Yu Tianheng's arms and pounded his chest over and over.
She could no longer hold back the hot tears brimming in her eyes, and they fell onto Yu Tianheng's neck.
Her voice trembled with sobs.
"You're not allowed to leave me for so long again. I was worried to death about you."
Only after he had spent a long time comforting her did Dugu Yan's sobs gradually subside.
Suddenly, Yu Tianheng spoke as though he had remembered something.
"Grandpa Dugu, the method I told you about before, forcing the toxins into a Soul Bone, might still only treat the symptoms rather than the root cause for you. After all, the toxins have damaged your body too severely. It can only ease the pain when the poison flares up."
"I have a way to completely remove the harmful toxins from you and Yan Yan. The toxins left behind won't just be harmless to your bodies; they'll also ensure the power of your poison techniques."
At those words, Dugu Bo immediately perked up.
Half a month ago, he had indeed followed the method Yu Tianheng had described.
Had he done so decades earlier, it might actually have succeeded completely.
But years of corrosion by the toxins had already affected every inch of his meridians, flesh and blood.
If he could remove only the harmful toxins, as Yu Tianheng said, his strength would definitely rise to another level.
He would no longer remain stuck at this level, unable to advance even half a step.
"Tian Heng, Grandpa trusts you. Whatever method you have, go ahead and use it. These old bones of mine aren't afraid of a little experimentation."
Seeing that Dugu Bo agreed, Yu Tianheng motioned for the two of them to sit down where they were.
Dugu Yan had also finished absorbing the left leg bone prepared by the Blue Lightning Tyrant Dragon.
"Grandpa Dugu, forgive me."
Yu Tianheng reached out and placed his hand on top of Dugu Bo's head, nowhere else.
After all, the only Soul Bone Dugu Bo possessed was a skull bone, and quite a lot of the toxins had already been forced into it.
